Induction Heating

™
One ProHeat System — Four Basic Induction Heating Configurations
ProHeat 35 induction heating systems solve preheating, post weld heat treatment (PWHT) and stress relieving problems.

Liquid-Cooled Cables See literature IN/15.0
Preheat applications up to 1,450 degrees Fahrenheit (788°C).
A highly versatile tool for preheating, stress relieving, hydrogen bakeout, post
weld heat treatment and shrink fit in a variety of pipe diameters and flat plate
Designed with flexibility in mind, the ProHeat liquid-cooled induction heating
cables can be wrapped into coils of various shapes and sizes to fit almost any
induction heating application

Liquid-Cooled Rolling See literature IN/13.0
Preheat of moving parts up to 600 degrees Fahrenheit (315°C).
Ideal for preheating rolling pipe and moving parts, with easy and time-saving
setup and movement for maintaining and adhering to preheat and interpass
temperatures
Enables the benefits of rolled pipe welding while also addressing some of the
concerns associated with other popular heating methods, such as open flame
and resistance heating
Optional infrared temperature sensor can read the temperature on the moving
part from 212–750 degrees Fahrenheit (100–400°C)
Optional travel detect system can be used for setting different heating rates/
ramps based on workpiece speed travel — when no movement is detected the
system turns off the output preventing damage to workpiece and rolling inductor

Air-Cooled Blankets See literature IN/14.0
Preheating applications up to 400 degrees Fahrenheit (204°C).
Air-cooled blankets are available for pipe diameters from 8–60 inches
(20–152 cm), or in the case of plate the lengths are 41–205 inches (1–5.2 m)
The blankets easily conform to circular and flat parts and install in a matter
of seconds
Manufactured from durable high-temperature materials, flexible induction
blankets are designed to withstand the tough conditions in both industrial and
construction applications

Air-Cooled Cables See literature IN/14.0
Preheating applications up to 392 degrees Fahrenheit (200°C).
Air-cooled cables are available in lengths of 30 foot (9.1 m), 50 foot (15.2 m)
or 80 foot (24.4 m) for flexible configurations
Designed with flexibility and efficiency in mind, the air-cooled cables can be
wrapped into coils of various shapes and sizes to fit almost any induction
preheating application, without the need for cooler and coolant
Air-cooled cables provide the same flexibility as liquid-cooled cables for preheating
